Polyvinyl alcohol (PVA) is a unique polymer with strong water solubility and film-forming capabilities. It is used extensively in the textile industry as a sizing agent to improve yarn strength, aiding in the weaving process. Additionally, PVA is used in the paper industry as a coating binder, where its excellent adhesive properties enhance paper strength and resistance. Its application extends to the medical field, where PVA is utilized in the formulation of controlled-release drug delivery systems.
